Abstract
The utility model provides an instantaneous horizontal open-type bleeding valve comprises a valve body, a valve cap, a four bar linkage mechanism and a driving element. The four bar linkage mechanism is rectangular or approximate rectangular in structure and comprises two frame connecting rods, one connecting rod and the valve body used as a stand frame. The driving element functions on one of the frame connecting rods and the connecting rod is connected with the valve cap. The utility model is applicable to air discharging for pressured air and especially applicable to furnace roof gas discharging of a double-bell blast furnace. The bleeding valve with long sealing life can keep the furnace roof pressure of the double-bell blast furnace is higher than the normal pressure, thereby obviously enhancing product output, reducing coke ratio and furnace blowout. Furthermore, when not driven by counterweight hydraulic pressure, the utility model has compact conformation, small volume, light weight and is convenient to install needless utilizing blast furnace platform to fix any components.
Description
Technical field
The utility model relates to a kind of gas and diffuses valve, is applicable to diffusing of compressed gas, and more particularly, the utility model relates to a kind of instantaneous horizontally openable that the two clock top gases of metallurgy industry diffuse and diffuses valve.
Background technology
Existing pair of clock top gas diffuses valve and generally adopts lever flip-shell structure, compresses, seals by counterweight, and counterweight and valve gap are driven by hydraulic pressure or electrical hoist.Because valve gap is opened moment, there is the angle of tumbling, cause a side of opening earlier, suffer the purging abrasion of raw gas inevitably, gas leakage when causing valve gap to be closed makes that sealing contact surface is very fast to be corroded by raw gas.The life-span of this valve is very short, has only one, two month.
Summary of the invention
For overcome existing diffuse the valve life-span short, sealing surface wear soon, easily leaks gas and lose the deficiency of furnace top pressure, the utility model provides sealing life long a kind of instantaneous horizontally openable to diffuse valve.
The utility model is achieved through the following technical solutions.
A kind of instantaneous horizontally openable provided by the utility model diffuses valve, form by valve body, valve gap, four-bar mechanism and drive element, valve gap, drive element connect by four-bar mechanism, four-bar mechanism is rectangle or approximate rectangular structure, the valve body that two side links, a connecting rod is arranged and use as frame, drive element acts on one of them side link, and connecting rod links to each other with valve gap.It is instantaneous that valve gap is opened, its distance that raises less than the 20mm scope in, the level difference that end any horizontal shift in valve gap limit is not more than 1.00mm, valve gap is not more than 3.00mm.Drive element can adopt the electronic cylinder mode of the hydro-cylinder of not being with counterweight or band self-locking, also can adopt the mode such as electronic, pneumatic of band counterweight.
The beneficial effects of the utility model are valve bonnet seal life-span length, keep two clock blast furnace top pressures to be higher than normal pressure, thereby significantly improve output, reduction coke ratio, the minimizing stove dirt amount of blowing out; During no counterweight hydraulic drive, compact construction, little, in light weight, the simple installation of volume do not need to utilize the blast furnace platform to fix any parts.
Description of drawings
Fig. 1 the utility model structural representation.
Fig. 2 is the structural representation under the four-bar mechanism closing condition.
Among the figure be respectively: 1: valve body, 2: valve gap, 3: four-bar mechanism, 4: driving mechanism.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
A kind of instantaneous horizontally openable diffuses valve, is made up of valve body 1, valve gap 2, four-bar mechanism 3 and drive element 4, and valve gap 2, drive element 4 connect by four-bar mechanism 3.Four-bar mechanism is rectangle or approximate rectangular structure, and two side link a, b are arranged, a connecting rod c, and the valve body of using as frame 1, and drive element 4 acts on one of them side link a, and connecting rod c links to each other with valve gap 2.Valve gap 2 is opened instantaneous, its distance that raises less than the 20mm scope in, the level difference that end any horizontal shift in valve gap limit is not more than 1.00mm, valve gap is not more than 3.00mm.Drive element 4 can adopt the electronic cylinder mode of the hydro-cylinder of not being with counterweight or band self-locking, also can adopt the mode such as electronic, pneumatic of band counterweight.
